Recently, it is proved that SP is also involved in pain modulation, acupuncture analgesia and immunoin- hibition. However, the role of CGRP in them is unclear Therefore, the dy- namic changes of CGRP-, SP-like immunoreactivity and expression ofα- CGRP,β-CGRP mRNAs in dorsal root ganglion and spinal cord in the arthritic rats were observed by using immunohistochemistry and in situ hybridization techniques combined with behavioral tests, respectively. Subsequently, the effects of this peoptide on the develoment of polyarthritis were investigated by intrthecal injections of CGRP and its antagonist in the rats. In addtion, GAL is a novel neuropeptide which coexists with CGRP and SP, but it may play a different role in the primary sensory system. Thus, we also observed the changes of GAL and GAL mRNA in DRG neurons and the spinal cord. The results were as follows

为此本文拟在大鼠佐剂性关节炎模型上，结合行为学测定、用免疫组织化学、原位核酸分子杂交技术观察脊髓背角及DRG中CGRP、SP、α-CGRP mRNA、β-CGRPmRNA的动态变化及电针的影响，此外，用鞘内和外周注射CGRP的工具药探讨了CGRP在佐剂性关节炎发生发展中的可能作用；甘丙肽（Galanin，GAL）也是新近发现的一个神经肽，并与CGRP和SP共存于DRG及初级传入末梢中，在神经损伤模型中脊髓CGRP、SP减少，GAL则明显增加，显示GAL与CGRP和SP的作用可能不同，因此在佐剂性关节炎模型上也同时观察了GAL和GAL mRNA的变化，实验结果如下

目的研究实验性犬急性重度马尾神经压迫48h的相关脊髓和背根神经节（dorsal root ganglion，DRG）内脑源性神经营养因子（brain-derived neurotrophic factor，BDNF）蛋白表达水平。

In rats receiving infusion of 100 μl of 2%formalin into the urethra, a large number of FOS-positive neurons were seen in the lumbosacral cord segments (L6 and S1), and they were primarily distributed in the medial dorsal horn and dorsal commissural nucleus.

在向大鼠尿道内导入100 μl 2%福尔马林后，大量FOS阳性神经元出现在脊髓腰6和骶1节段的后角内侧部和后连合核内。

Therefore, in the present study, a retrograde and anterograde experiments were made in the rat to address this issue. After injection of cholera toxin B subunit, a retrograde tracer, into Barrington's nucleus or D-region, some retrogradely labeled neurons were found in lamina I, sacral parasympathetic nucleus and dorsal commissural nucleus of the lumbosacral spinal cord segments. Injection of biotinylated dextran amine into lamina I, sacral parasympathetic nucleus and dorsal commissural nucleus, respectively, a large number of BDA-labeled axon terminals were seen in Barrington's nucleus and D-region.

Immunoelectron microscopic examination revealed that mGluR5 was prominently located in some neuronal somata and a lot of dendrites within the superficial layers of the spinal dorsal horn. Some dendrites containing mGluR5 constituted synaptic glomeruli with the terminals exhibiting the morphological characteristics of primary afferent C fiber. The ultrastructural features indicated that mGluR5 in the dorsal horn of the spinal cord may prominently work as a postsynaptical receptor to mediate or modulate the function of glutamate in the primary sensory transmission, including the nociceptive transmission.

免疫电镜研究显示，在脊髓背角浅层内，mGluR5主要定位在部分神经元胞体和大量树突内，并常见部分含mGluR5的树突与具有一级传入C纤维终末形态特征的轴突终末构成突触小球。mGluR5在脊髓背角浅层内的超微定位特征表明，脊髓背角内的mGluR5可能主要作为突触后受体介导或调节谷氨酸传递一级感觉的功能。
